Proof step 22 from proof countrefs-getdims (previous step)

countrefs(getdims(ints0)) = countrefs(ints0) ⊦ countrefs(getdims(i ' + ints0)) = countrefs(i ' + ints0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ 0 < j → getdims(j ' + ints) = j ' + getdims(ints)
Proof step 11:
¬ 0 < i, countrefs(getdims(ints0)) = countrefs(ints0) ⊦ countrefs(getdims(i ' + ints0)) = countrefs(i ' + ints0)
Proof step 21:
0 < i, countrefs(getdims(ints0)) = countrefs(ints0) ⊦ countrefs(i ' + getdims(ints0)) = countrefs(i ' + ints0)

Rule argument

[crewrite-arg: getdims-rec, F, [ints, j] → [ints0, i]]
